pc-nrfutil 2.1.0 SDK12 serial dfu

[Sergy]

Hello,

I saw that there is now serial dfu option enabled and Id like to make a serial DFU bootloader, however its a bit hard to read this Python code. Would be amazing if somebody could give the serial protocol that is used for transmissions? Also may be somebody knows how the .dat file is being read and transformed into Init packet?

Thanks!

Hello, we plan to add serial dfu over UART in upcoming SDK release, but documentation is not ready yet. The packet format will however be quite similar to our existing BLE transport .

I have already made an experimental example of serial DFU based on an early beta release of the official uart transport. Have attached it here in case you want to try it.

ok, could be related to board differences. Do you have a DK you can test with? If not, what do you use for USB<->UART bridging? Also, is flow control enabled/disabled?
